I just got the Obsidian - I like the page turn buttons. They are just a tad better than the first Nook wifi, but if you read while you are eating, it keeps greasy paws off the screen.

The flat bezel keeps the crumbs out, too. You can adjust lights. The flat bezel also keeps out cat hair. My cat likes to read along and she sheds.

I found what came on it adequate. I can read all the books I had stashed, and can transfer them from the computer through a couple of methods since it does use a micro SD card. I'm not sure where the appmarket the inkBOOk uses is located. The book itself is Polish and has many languages.

I'm finding it a big plus NOT to have Google on the device. I refuse to buy books from Google. I think the appmarket might be a standard for non-Google play devices. I had Chinese Coby tablets with no Google and no problem.

It does have other readers in the repository, and they are the standard ones like FB, Cool, Aldiko, Moon.

Compared to a tablet, it's much clunkier and slower than my phone or Tab4. It might not have all the niceties of the branded readers, but it is doing just fine for me.
